'Referring to the drawings, a device isV shown adapted to be supported upon or adjacent the top of amilk can such as illustrated asl() in Fig. 1. p

While the device can be thus variously supported, in the embodiment of the invention illustrated the same is shown as ing spaced rods or Lwires 11 adapted to extend across the top of the can 10, ateach' side of the center thereof and having their ends bent downwardly as shown at 11a at the edge of the can. Supported upon and secured tothe wires or rods 11 in any suit-I able manner, as by spot-welding, are a pair of substantially concentric cylinders 12 and 13 spaced yslightly apart to form ay narrow annular chamber 14. Cylinders 1Q and 13 are connected at their bottoms to kclose the bottom ofthe chamber 13 and a partition 15 is shown adjacent the top of said cylintop of the chamber 14. The cylinders 1,2 and 13 are provided on their outer and inner surfaces respecchannels and while these tending grooves or' dimerit l if as corrugations extending helically about said cylinders. The cylinders 12 and 13 as shown extend a short distance above the partition 15 thus forming a trough 16. Another pair of cylinders 17 and 18 which are substantially concentric, are spaced a short distance to form a chamber 19 therebetween closed at its topv and bottom by flanges connecting the cylinders 17 and 18. Cylinder 17 is of somewhat greater diameter than cylinder 12 so that the same is spaced a short distance outwardly of the cylinder 12. Cylinders 17 and 18 are shown as supported from the cylinder 12 by channel members 2O extending between cylinders 12 and 17 at the tops and'bottoms thereof. A pipe or conduit 21 extends into the bottom ofthe chamber 1e? through uthe cylinder 12 which is adapted to have another pipe or tube 22 connected thereto, which will in turn be connected to some source of water supply orsupply of other cooling medium. A pipe or conduit 23 extends into the opposite side of the chamber 14V through the cylinder 12 and is bent at rioht angles and extended to a pointy adjacent the top of said chamber. The tube 23 is also adapted to be connected to a pipe or tube y2li through which water may be discharged from. the chamber 111-.

-ing a pipe or tube f other coolingf medium.

`tially spaced brackets 30. Th vvex surface of thev member 29 preferably is pipeor conduit 25 also extends into the bottom of the chamber 17 through the cylin` der 18 adapted to have the pipe or tube 26 connected thereto which will extend to some suitable source of water supply or supply of An outlet pipe 27 extends from the top ofthe chamber 19 through the cylinder 18 also shown as hav 28 connected thereto throughv which the cooling medium may be discharged 4from chamber 19. The trough 16 has a multiplicity of small holes 16a extending therethrough at the inner and outer side thereof and closely adjacent the partition 15, which holes preferablyA will taper somewhat toward their outer ends and which will also refer-ably aline with the grooves or channell formed in the surface of the cylinders 12 and 13.

A member 29 of downwardly flaring shape is provided, having a lower terminal vedge spaced above the trough 16 and substantially alined with the center thereof and while member 29 may be variously shaped, in the embodiment of the invention illustrated it is shown as substantially seini- `spherical inform and supported yfrom the cylinder 13 by a plurality'of circu1nferene upper or conformed with a plurality'of downwardly extending'y channels or grooves 291-and while these maybe variously arranged, in the embodimenty of the invention illustrated they are shown as extending helically downward from the central portion thereof, as illus `at its upper trated in Fig. 2. A plurality of circumferentially spaced strips or brackets 31 extend from the top of are secured tothe outside of and support a liquid receiving tank or receptacle 32. The tank 32 is shown as substantially cylindrical end, having an intermediate conicalr portion-,leading to a smaller cylindrical portion 32a having a slightly curved bottom. The lower has an opening 32b extending therethrough. A float 33, shown as substantially cylindrical in form and ofsnialler diameter than portion 32a, is disposed in said portion and said float has spaced radially extending ribs 33a engaging the wall of the portion 32aL to keep the float centrally disposed there. Float 33 is somewhat curved and tapered at its lower end and lits in and closes opening 321.

In `lFig. '8 the device is shown Vsimilar in all respects to' the device above described, exceptthat the cylinders 17 and '18 are ,supported upona flange 40a of a pan l0 through the walls of which the pipes 21 and23 ex'- tend. The pan 1l() has a delivery spout 40" extending from one side thereof. Y

In operation thedevice willbe disposed over the milk canas shown, with the recep tacle 32 disposed under the cream spout of the sepzfirutor. Water or other cooling medium will be circulated in chamber 14, entering through the pipe 21 and discharging from adjacent the top of said chamber through the pipe 24. A cooling medium will also be circulated in thechamber 19, entering through the pipe 25 and `discharging from the pipe 27. The cream will flow into the portion 32a of the member 32 and through the aperture 32h. Thelloat 33 will tend to cause an even liow of the liquid therearound and through the aperture 32". Cream will be discharged into'the vmember 29 and be distributed thereon in a comparatively thin film or layer and will flow through the grooves 29" Idown.vardlyf and outwardly on the convex'surfuce of member 29 and will drop from the lower terminal edge thereof into the trough 16. ldroinrthe part of the portionf32a down llo

trough 16 the cream will pass through the opening 16"L to the outer surface of the cylinder 12 and to the inner surface' of the cylinder 13 and will flow in a thin film or layer and through the grooves in said surface downwardly. The cream will drop from the ,lower edoes of the c 7lindcrs 12 and 13into chambers 16 and 19 l applicants invention, which,

device from any dust or dirt or other substance which might be carried in the atmosphere. i

In the modification shown in Fig. 8, the pan 40 will be supported in any suitable manner above the top of the cream can and the cream will be discharged from the bottom of cylinders l2 and 13 intothepan l() and will flow out through the spout lOl into the cieain pan. i

The device is quite simple lin construction, easily made and assembled andcan be conveniently disposed in position for use. The same has been amply demonstrated iii actual practice and found to be very successful and efficient.
